pressed against the edge of the cartridgei To all 'whom it may concern.'

Be it known that l, BAPTisT GoEnnL, en gineer and director, a sublect of the German 'L'. e. such fire arms, according to-which'a manipulation is necessary on the part of the marksman for closing the breech that is o ened by the action of the recoil. Al-

t ough the entire-automatic fire armlnaturally representsjln itself a great technical advancement, Iyet it cannot be denied that `this automatic function of the parts involves certain disadvantages when loading and closin'g the fire arm in so far as the iire a-rm is thus even when the marksinan has ceased iiring." Moreover, it is not ossiblevwith most automatic fire arms for t e marksman to ascertain for a certainty that the fire arm is actually loaded or not, be-

adk

'fio` l vcured in its outermost receded 4cause after the discharge of the last cartridge, the breech moves into the tiring position and it is therefore not readily obvious to the marksman that there are no more cartridges' left in the barrel. Thus a certain Want is felt especially in connection with iire 'arms for the general use of those not familiar with the handling of automatic loaders to employ. such automatic 'loading iire arms which are provided with an arresting or catch device for the breech, whereby the breech opening automaticallyv after each shot is seosition and only adapted t pass into the ocking ppsition4 when such device is released; the marksman'is thus ableto control the loading operation of the fire arm and especially to see immediately when the magazine of his i fire arm is empty. Thisrelease generally takes place Whenever the marksman inserts a new cartridge in the'cartridge chamber; it however also rests with the marksman to leave his lire arm unloaded or the breech empty (without cartridge) wlienhe does not Wish to shoot. -As in the older constructions lwherein4 the ,v extractors are actuated by a Aspecial spring, the claw of the extractor is Liege, Belgium, have invented certain new and useful lmproveg hammer and the closing'of -thelabutmentj1 of the through the instrumentality of the spring,

tension, the iiring pin in the present arrangement tends to positively move the extractor in opposition to the pressure of its springs into the operative position.

Now this invention has make' such semi-automatic firearm with a cylindrical breech of a very simple and 'handy construction adapted' for smaller weaponsv and made either as single loaders or equipped With aniagazine. .v

A carbine constructed with the improved breech mechanism is shown in the accompanying drawings, of which Figure l is the longitudinal breech mechanism of a carbine with main spring and locking spring arranged behind each other; Fig. 2 is a cross-section on line A-B; Figs. 3 and 4 are two modifications of an annular stop platev serving as abutment for the main spring; Fig. 5 is a longitudinal section of the ,cocked breech mechanism-` As compared with other constructions wherein thepercussion or striking mechanism surrounds the breech bolt and its locking spring, so that the locking spring is located within the niain spring, the construction shows the main spring and locking spring -arranged one behind the other. This construction affords besides other, advantages the safety pin protruding from the breech bolt. Moreover, the marksman is able to control the loading operation of the Jfre arm. The cocking of the firing pin can be eected by hand Without moving the breech bolt.

for its object tov especially carbines which areV section' of the of the fire arm by turning the firing.

The barrel a is rigidlysecured tothe rey,

ceiver. The'receiver is formed of tw'parts b and b1 screwed one Within the other and has a locking sleeve or socket?)2 against which the annular stop plate. m bears. This stop -plate has in the middle a bore m1 for the-passage of the iiring. pin f andtwo semi-circular slots fm? for the passage of the breech bolt c, Y

which is bifurcated in its rear'part. The firing pin f with its spring "u is mounted in the breech bolt -c. This main spring bears against the annular sto late m and against g pin. The abutment f1 also serves for keeping the iiring pin in the cocked position/.by engagement with the scar g1 of bhe/trigger g. The socket-head n is serred onfthe outer end of the .breech bolt c by means. of the bifurcated sleeve o, which islscrewed in the breech bolt. The ringpin carries on its outer end the stud or button 7L which is movably arranged by means of a pin p guided in a roove z of the ring pin. The button h is` attened laterally and Irests With this flattened part in the fork of the threaded sleeve o. (See Fig. 2).

The operation of thelre arm is as follows: Willen pulling back' the firing pin With the 'aid of the button h, the Amain Asprln Willbe compressed and the meehanism coc red (see F ig. 5). Ill/Then pulling the button 7L out further, its flattened part moves out of the Ifork of the sleeveo and when the button makes one quarter of a turn', the flattened part eX- l tends across the space between the legs of the fork and the safety of the fire arm is thus insured. The .breech bolt c protects in its front part the locking spring d which on the one hand bears against the end of the bore in thislbreech bolt and on the other hand against astop plateg (similar to the stop plate m).

The `part rot' the receiver bv serves' as abut.

ment for the stop late and the latter also checks the rearwar movement of the breech bolt. When the breech bolt c is Withdrawn by means ofthe button 7L, the locking spring d as Well as t sear g1, While when releasing the button 7L,

the breechbolt c is I noved forwardunder the he main spring o Will be compressed. The. ring pin f is secured by the What I claim as my invention, and desire' to secure by Patent is 4 l. In a ire arm, a cylinder, a cylinder lock, a closing spring therefor, a striker, and a main .spring therefor, said main spring being arranged at the rear of the both springs surrounding the striker.

2. In a ire arm, a cylinder look, a closing s ring therefor, a striker, and a main spring therefor, said main spring being arranged at the rear of the closing springv and both springs surrounding the strlker, and a' lock ease, said striker being extended through said look case at its rear.

3. In a fre arm, a cylinder lock, a closing spring therefor, a striker, and a spring therefor, said spring being arranged at Jche rear of the closing spring, the striker, and annular platesA serving as abutments for said springs, said plates bein adapted to permit said striker and lock to move backward freely.

f 4. In a iire arm,y a lock case, a cylinder look therein, a striker extendin to the rear of said look ease, and a latera ly flattened button at the rear end of said striker,v said button being adapted to be turned to hold said `striker retracted.
